Error c2061 when compiling

Question

When I compile a project I get this error:

The only thing I did was copy and paste ClassTwoPointOne files into ClassZero files and change names...

ClassTwoPointOne.h:

#ifndef CLASSTWOPOINTONE_H
#define CLASSTWOPOINTONE_H

#include "ClassTwoPointZero.h"

class CClassTwoPointOne : public CClassTwoPointZero
{
public:
    CClassTwoPointOne();
    virtual ~CClassTwoPointOne();

    virtual void SetFClass(void);
};

#endif // CLASSTWOPOINTONE_H

ClassTwoPointOne.cpp:

#include "stdafx.h"
#include "ClassTwoPointOne.h"

//////////////////////////////////////////////////////////////////////
// Construction/Destruction
//////////////////////////////////////////////////////////////////////

CClassTwoPointOne::CClassTwoPointOne()
{
    m_sEIAClass = "2.1";
    m_nScanTime = 0;
}

CClassTwoPointOne::~CClassTwoPointOne()
{

}

void CClassTwoPointOne::SetFClass(void)
{
    SendCommand( COMMAND_SET_FCLASS_2_1);
}

ClassZero.h:

#ifndef CLASSZERO_H
#define CLASSZERO_H

#include "VoiceModem.h"

class CClassZero : public CVoiceModem
{
public:
    CClassZero();
    virtual ~CClassZero();
};

#endif // CLASSZERO_H

ClassZero.cpp:

#include "stdafx.h"
#include "ClassZero.h"

//////////////////////////////////////////////////////////////////////
// Construction/Destruction
//////////////////////////////////////////////////////////////////////

CClassZero::CClassZero()
{
}

CClassZero::~CClassZero()
{
}

I don't understand whats wrong... anyone can help?

Thanks a lot

Answer 1

FaxAPI.cpp(143) : error C2061: syntax error : identifier 'CClassZero'

The error is at or near line number 143, in file FaxAPI.cpp. The error is related to the identifier CClassZero

(Possibly being undefined, or misused. Possibly something as mundane as a missing semicolon).

If you cannot find the error in FaxAPI.cpp yourself, you need to provide us with the relevant part of that file.

Answer 2

msdn says c2061: "The compiler found an identifier where it wasn't expected. Make sure that identifier is declared before you use it." So apparently class CClassZero became undeclared after you messed with the files, makesure that you include appropriate files and that they contain a valid declaration of class CClassZero
